Knock vs Plivo FAQ
- Which one is cheaper?
- Knock starts lower at $250/mo, compared to $1000/mo for Plivo.
- Can I use either one for free?
- Both offer free plans, so you can try each without paying. Start with whichever fits your workflow better and upgrade when you hit the limits.
- How do they charge?
- Different approach here. Knock uses hybrid pricing, while Plivo goes with usage-based. That changes the math depending on your team size and usage.
- Which one is a better deal?
- Depends on what you need. Knock: Knock sits mid-market — not a cheap commodity API, but not pricing like Braze or Iterable either. They're courting engineering-led teams who want notification infrastructure that's more sophisticated than rolling their own, without paying enterprise-messaging-platform prices out of the gate. Plivo: Sits in the same CPaaS bracket as Twilio and Vonage — not the budget option, but competitive on a per-message/per-minute basis and more transparent than most about starting Enterprise pricing. They're chasing developers who want Twilio-like power without getting nickel-and-dimed on add-on fees.
